PCM Help

[[Jo...]]

Hey guys I am trying to write some PCM to update a tolerance depending on P/N. I have done this before but am not getting the expected output. 

MyPick=inquireList("Select Part #","CS_8S_20-40T_Op50","32654002","31825615","32651734","32651735")

	if MyPick=="CS_8S_20-40T_Op50"
		then
			RndTol11=="0.04" 
			RndTol242=="0.03"
		else
			RndTol11=="1.8"
			RndTol424=="1.3"
	endif

right now, I am getting an error "Parameter: then is not defined".

I tried to remove the "Then" and when trying to display the variables I get an "a Zeiss.calypso.OMParameters" error.

It has been a while since I dived into PCM. It is probably a simple syntax issue, as this is pretty basic.

 

Appreciate the help.

    if MyPick=="CS_8S_20-40T_Op50"
        then
            RndTol11="0.04"
            RndTol242="0.03"
        else
            RndTol11="1.8"
            RndTol424="1.3"
    endif

change "==" to "=" when setting variables, "==" is used when comparing.

 

Also, you probably want to remove the quotes on those tolerance values, quotes makes it a string, no-quotes would make it a number.

That worked! I did have to just remove the "Then" as well.

Thank you

Also as an FYI I am not aware of any need for the use of the "then" statement inside of the "if" statement. 

I do see that it is a valid statement, so I'm not certain as to what the use cases are for when you would need it, maybe it's not inside of an "if" statement. 

 

Also also, you might want to look into using selectCase instead - mainly for the ability to have parameter files that you can easily update with variables instead of having them hard-coded into the measurement plan.

I got my programming/syntax mixed up when I was adding in the "Then" I believe.

I have used parameter programming for a few applications. I remember programming 10-12 bearings on 1 program with different dimensions. It was a good application. 

 This was just a one-off update.

There is also the selectCase pcm, which can be very useful. It is especially useful for having multiple selections to avoid multiple "if then" or nested "if" statements, and it is also more flexible if you need to expand the options list in the future

Example from the Calypso help menu
 

 

selectCase number
      case is <= 0
            Message = "Number is too small"
      case 1, 2, 3
            Message = "Number is smaller than 4"
      case 4 to 7
            Message = "Number is between 4 and 7"
      case is >8 AND number < 11
            Message = "Number is 9 or 10"
      caseElse
            Message = "Number is outside the range"
endSelect
